The landing gear struts are pretty easy to make once you have a good method. My first one ended up with one hole drilled off-center. These are made from the RS-402 that is also used on the fin. Aluminum fin strut brackets to the rescue!
To get the hole drilled on center put one of the fin strut brackets between the axle and the strut, be sure to align the hole in bracket with hole in axle. The fin strut bracket is on drawing 10 bottom right.
Align the drill bit through the axle and bracket hole, then drill through the strut. Be sure to keep the bracket flat against the axle.
This is what the brackets look like.
